    An easy test to check the wiring is to disconnect it from the actuator on the front diff. If it no longer blows the fuse when you put it in 4WD, then the actuator itself is bad.
    If it still pop's the fuse, start checking the wiring beween the switch on the T-case and the actuator plug (where you disconnected it.)
